| Abstract: | The Suzuki coupling reaction of 3,5-dichlorobenzoic acid and 2-bromo-4-methylpyridine upon sodium tetraphenylboron was carried out in an aqueous medium catalyzed by palladium chloride with the addition of a co-catalyst dosage of surfactant.The effect of reaction conditions such as the dosage of surfactant and the reaction temperature on the proceeding of reaction was discussed.When 0.05 mmol of TEBA was added to the organic solvent-water medium system,the dosage of palladium chloride used as the catalyst fo... |
